The TESSERA NDB-2 represents a significant departure from conventional shock weapon design. While it does deliver a conventional electrical discharge sufficient to cause muscular disruption, its primary engineering achievement is a secondary emission system that produces a precisely tuned electromagnetic pulse in the 1.2–4.8 GHz frequency range — the operational band of approximately 94% of commercially available brain-computer interface hardware. On contact, the NDB-2's pulse propagates through the skull via conductive gel reservoirs embedded in the contact prongs, inducing signal noise across active neural mesh networks and causing temporary interruption of BCI function lasting between thirty seconds and four minutes depending on implant generation and shielding quality.

The subjective experience reported by subjects is described variously as 'white noise in the skull,' 'watching your thoughts go offline,' or simply 'the worst headache of my life arriving all at once.' For individuals whose BCIs are deeply integrated into motor function, proprioception augmentation, or pain management, the disruption can be profoundly disorienting — effectively rendering a high-chrome individual temporarily unable to coordinate their augmentations during the window of neural static. TESSERA markets the NDB-2 to corporate security units, executive protection details, and Arcturus-affiliated contractors, positioning it as a tool for safely detaining augmented subjects without escalating to lethal force.

The NDB-2 is not without controversy. Civil liberties advocates have challenged its use against BCI-dependent individuals with medical implants — pacemaker-adjacent neural regulators, seizure suppression systems, and chronic pain management arrays have all been documented to suffer damage or dangerous interruption from NDB-2 contact. TESSERA's response has been to update the frequency discrimination software in subsequent firmware revisions, a solution critics describe as insufficient and legally convenient.
